Santa Clara County Supervisor Cindy Chavez was credited with crafting a resolution, according to the Sunnyvale Employees Association.

SEA officials on Friday rejected the city's last financial offer, effectively ending last-minute negotiations between the two sides. With no agreement in place, the employees union and its members planned to not return to their posts after 12:01 a.m. on Monday, sources said.

On Sunday, Mayor Glenn Hendricks described what people could have expected had the strike prolonged.

"An impact will be on our planning department, people who are getting inspections if they are doing home remodeling, library services and parks," he said.

Sunnyvale city leaders said they offered workers a "10 percent raise, a continuation of paying a 30 percent pension contribution, and a $6,000 signing bonus to employees who make an average of more than $120,000 in salary and benefits." Union leaders rejected that proposal.
